Abstract
The invention discloses a pesticide composition containing mesosulfuron, pinoxaden and florasulam. The mass proportion of the mesosulfuron, the pinoxaden and the florasulam is (1 to 20) to (1 to 20) to (1 to 20). The pesticide composition disclosed by the invention is applicable to control annual grassy weeds and broad-leaf weeds in the wheat field. The pesticide composition disclosed by the invention has the obvious synergistic action and the used amount of effective components is obviously reduced than single use of the effective components.
Description
Technical field
The composition pesticide that the present invention relates to, be with mesosulfuron, azoles quinoline grass ester, florasulam for active ingredient, for preventing and treating farmland weed, be particularly useful for preventing and kill off wheat paddock annual gramineous weed and broad leaved weed.
Background technology
Chemical method weeding is agriculturally one of Main Means controlling weeds.In recent years, because some weed killer herbicide kind large area are used alone, a lot of weeds have been caused to develop immunity to drugs.Simultaneously, grass when weeds occur is mutually complicated, not only annual and perennial weed is mixed raw, draft, liana and shrub have concurrently, and weeds emerge uneven, seed, low age, the staggered generation of weeds at advanced age, so when weed killer herbicide kind is used alone, defect in a certain respect and limitation all can be shown.
Mesosulfuron is sulfonylurea internal-suction type efficient wheat field herbicidal, has obvious preventive effect to the grassy weeds such as Triticum tauschii, wild oat, bromegrass, Alopecurus and multiple broadleaf weed.Be a kind of novel compounds, its active ingredient can be absorbed by the root of weeds and cauline leaf, by suppressing the activity of acetolactate synthestase in weeds body, destroying the normal Physiological and Biochemical Metabolism of weeds and playing activity of weeding.Effectively can prevent and kill off wheat paddock major part grassy weed, simultaneously also can effective control section broad leaved weed.Young tiger tiger can very fast metabolism in wheat body, has fabulous safety to wheat.
Azoles quinoline grass ester belongs to neophyl pyrazolines weed killer herbicide, and the mechanism of action is acetyl-CoA carboxylase (ACC) inhibitor.Cause fatty acid biosynthesis block, make cell division stop cell membrane destructurized containing fat, cause weeds dead.Have Uptake and translocation, be mainly used in wheatland and prevent and kill off annual gramineous weed, through toxicity test and field control effectiveness test, result shows wheatland annual gramineous weed as wild oat, green foxtail, barnyard grass etc. have good preventive effect.
Florasulam is triazolopyrimidine sulfonamides super-high-efficient weed killer herbicide, and florasulam is inner-adsorption conduction-type herbicide, can conduct to weeds complete stool, and thus herbicide is thorough, can not recur.Efficacy stability at low temperatures, even still can ensure stable drug effect 2 DEG C time, this point is that other weed killer herbicides are incomparable.Broad leaved weed is prevented and kill off for wheat paddock.
During the single use of mesosulfuron, azoles quinoline grass ester, florasulam, all there are certain defect and limitation.
The mixture of the present inventor to mesosulfuron, azoles quinoline grass ester, florasulam conducts in-depth research, on the basis of a large amount of formula indoor screening tests and field medicine effect test, discovery mesosulfuron, azoles quinoline grass ester, florasulam carry out mixture, within the scope of certain mixed ratio, obvious synergistic effect is shown to weeds of wheat, after further study, the present invention is completed.
Mixture and the application of mesosulfuron, azoles quinoline grass ester, florasulam there is no report at present.
Summary of the invention
The object of the invention is to solve in prior art to farmland weed develop immunity to drugs problem and actual control efficiency poor, provide a kind of efficient, low toxicity, quick-acting are good and the lasting period is long, are conducive to the composition pesticide of the farmland weed comprehensive regulation.
Another object of the present invention is to provide and is used for preventing and kill off farmland weed by this composition pesticide, is particularly useful for preventing and kill off wheat annual gramineous weed and broad leaved weed.
Technical solution of the present invention: a kind of composition pesticide containing mesosulfuron and azoles quinoline grass ester and florasulam, with mesosulfuron, azoles quinoline grass ester, florasulam for active ingredient, the mass ratio of mesosulfuron and azoles quinoline grass ester and florasulam is 1 ~ 20:1 ~ 20:1 ~ 20.
Composition pesticide of the present invention is prepared into any one formulation being applicable to agriculturally using by known method, reasonable formulation is the one in wetting powder, suspending agent or dosage form of water dispersible granule.
The auxiliary agent used in composition pesticide of the present invention comprise solvent, dispersant, stabilizing agent, emulsifier, antifreezing agent, thickener etc. and other to be of value to active ingredient stable and play the known substance of drug effect in the formulation, all various compositions that are conventional in pesticidal preparations or permission use, be not particularly limited, concrete composition and consumption are determined by simple test according to recipe requirements.
Product described in the invention can the form of finished product preparation provide, and namely in composition, each material mixes, and the composition of composition also can the form of single dose provide, and directly mixes in tank or bucket, be then diluted to required concentration before using.The frequency of administration of the present composition and amount of application change with weather condition and crop condition change, can by the object using suitable formulation to reach control.
Composition pesticide of the present invention is applicable to the control annual broad-leaved of wheat paddock and part grassy weed.
Compared with prior art, beneficial effect of the present invention is, composite have obvious synergistic effect, improves control efficiency; Expand control spectrum; Two kinds of active ingredients are composite, reduce Pesticide use amount, thus reduce cost and decrease the pollution to environment.
